Taped it last night (as I was out) and have just had a good look at the bus. Although it is obviously supposed to be a Routemaster, I think it is just a set. Some things just aren't quite right. The steps are too close to the platform edge and are not steep enough, there is no room for the back seat by the top of the steps, the rear 'skin' of the bus is too thin. I could be wrong, but just doesn't look quite right. I will now go and take my anorak off!!
